Application ,led September 4, 1913. Serial No. 788,179.

To all whom it may concern.'

Be it known that I, FRANK L. CAPPs, of Bridgeport, Connecticut, have invented a new and useful Improvement in Ejector Mechanism for Cylindrical Records, which invention is fully set forth `in the following specification.

he present invention relates lto talking machines, and particularly to ejector mechanism for removing. the cylindrical recordsV and vblanks from the mandrel.

The object of the present invention is to provide a simple device which may be readily manipulated and which will be durable and effective in operation, the parts of which are compact and assembled.

drical form of records or tablets, the mandrel of the machine and the interior of said records or tablets have a slight taper. lVhen the record or tablet is in operative position. it fits tightly upon the mandrel and revolves therewith, but a slight longitudinal movement of the tablet tends to free it from frictional'contact with'fthe mandrel, and it may then be readily removed. by hand. AThe tablet must fit firmly on the mandrel when in voperative position, and being of wax or wax-like material, is

-liabl'eto be broken or injured in imparting the initial longitudinal movement thereto to remove it from the mandrel.

by means of lever mechanism which is open to several objections. It is liable to damage the tablet, is more or less inefficient, and is in an exposed position where it is inthe way of the operator in manipulating the machine.l I

present invention is to means for imparting provide an eli'cient starting movement to the the initial or tablet, which means shall be free from thev objections above indicated, and with this object in view, the invention consists, generally'stated, member placed preferably within the interior of the mand ing therewith but capable, under certain conditions, of vlongitudinal movement with relation to the mandrel andv provided with an outwardly projecting member or mem-A e5 b ers 'for engaging the record during said out of the way," said parts being readily assembled and dis- It has" heretofore been proposed to' 'effect this -initial or loosening-longitudinal movement rel revolvlongitudinal movement and imparting the initial or starting movement thereto.

The invention will be better understood by reference to the accompanyin drawings,'illustrating one expression o the` inventlve idea, and wherein, l'

Figure l is an elevation, partly in ysec-4 tion, of the mandrel, the record mounted thereon, 4and the means for ejecting the record from the mandrel, the parts being 1n the position which they occupy during .the normal operation of the machine, that 1s to say, when a record is being made o1' reproduced; Fig. 2 is a View similar to Fig. 1,: except that the,l parts are shown yin the position which the mechanism has been cylinder may be readily removed by introducing and Fig. 3 is a detail perspective showing the record-em gaging members and associated parts. v 'Referring to the drawings, wherein like reference numerals in the several figures in dicate like parts, 4 is, part of the motor casing to which is connected, preferably integrally, an extended tubular bore 5. Within the casing 4 is mounted a bushing 6 and within the bore 5 a bushing Y, through which bushings passes the shaft 8 which is carrying a bushing 14 with 4which shaft 8 also engages, and havinga portion project-A ing beyond spider 12 on which portion isV screw-threaded a thumb-nut l5 which isv secured to shaft 8 by a pin 16 projectingl through a perforation in said shaft 8. When the pin 16 is in place, it will bea preciated that shaft 8 is prevented from moving toward the left, and in order to` prevent the shaft from moving toward the right, it is provided with anenlargement at 17, which enlargement engages bushings 7 and14.-. j

At its inner'end the mandrel 10 is 'provided with y an outwardly proj ecting flange' 18, the mandrel andsaid` ange being slotted at a; plurality of points to permit of movement longitudinally -of said-'lmandrel of members 19 which engage .the inner end of, the record-and are "operated to mo've said record' long itu,dinally of the mandrel. During the-normal operation of the machine, clock-wise direction to the nut 15 which is that is to say, when a record of sound is bescrewed onto the sleeve 13 of the mandrel in recorded on a blank or reproduction is 10. This effects a rotation of the mandrel being elfected, the parts are in the position 10 and kwith it the record-engaging memindicated in Fig. 1, the inner end of the bers 19, sleeve 23 and flange 24, and by rea 70 record contacting with the layer 20 of felt son of the fact that the flange 24 is conor other suitable material which is secured tinuously in engagement with the disk 37, tothe flange 18, the record-en aging memthe latter is rotated on its own axis and is bers 19 at this time being out o engagement also forced to travel along the cut-away with the end ofthe cylindrical tablet.
